APPLIANCE FOR USE IN HAIR wAvING Filed Aug. 25, 1951 2 Sheets-Sheet 2 Patented Apr. 18, 1933 [U A E PATENT 1 WILLIAM MACDONALD-Ann HUGH MACDONALD. or mvnnnnss'soo'rmn isrrnimvon FOR, USE IN-HAIR..WAVI1\TG Application filed August 25,1931, Serial No. 559,304, and in Great Britain AugustSO, 1930. I .12;

This invention relates to apparatus for use in hair-waving of the 'type wherein steam is injected into tubes/or jackets thereby subjecting the hair, which has been previously wound onto curlersand placed inside the jackets, to a moist heat and ste'am treatment.

The objectgof the invention istoiprovide improvements in appliances for'the generation of the steam andthe conveyance thereof from the generator to the waving device.

The invention is concerned more particularly with apparatus in which a plurality of steam generators is provided one] for each waving appliance, as shown in our British .15 Patent No. 207 ,248, and an of the invention is to provide improvements in steam generators whereby the heating'arrangements are-simplified. L 7 l 7v The boilers areheatedby electrical means '20 and in order that the coupling of the various heaters may be simplified, according to the invention'each boiler is provided with a valve devicewhereb an alternative path for the steam is availa lefrom the boiler so the I flow of steamtof the waving appliance may "be cutoff as desiredwithout the necessity of cutting out the heater concerned. By such arrangement the heaters may be coupled up in series, thereby simplifying the Wiring.

A further feature according to the invention consists in forming each boiler'with a steam dome comprising a part projecting above a substantially. horizontal wall in which a filling aperture is provided thereby facilitating filling ofthe water space to the desired level.

' Further features of hereinafter described. In the accompanying drawings'' 7 Figure 1 is a sectional elevation of the improved boiler according to'the invention.

Figure 2 is a plan thereof. a Figure 3 shows aboiler mounted in a supporting tray or container.

the invention will be Figure dis a partial plan showing a num ber of boilers in position in the tray.

Fig. 5 is a vertical sectional view on the line 5 5o fFig.1. 7 F 'In carrying the invention into Iefi'ect ac- 0 cording to one convenient mode,'a series of ers 6 being arranged around the outer rim or wall so as to form a circular series. 'The boilers are preferably tapered in plan as seen in Figure lso asto make use ofthe'a-vailable space, while the tray may be ofany suitable construction. and. is preferably of the form described and claimed. in our British patent application No. 18,913 of 1931 I V The tray is provided with a gutter 7 formedas an annular depression in the lower wall thereof, such gutter being located below the ring of boilers. A suitable outlet 8 from r a the gutter is provided to carry away to waste anywater collected therein to a waste water vessel 9 which may be detachably mounted beneath the outlet. By means of thegutter any wateroverflowing from the boilers during filling will be immediately collected'and carriedaway' P f... Eachboil'er is formed a steam dome 10 to whicha suitable safety valve 11 is attached. This dome is formed so thatahorizontal wall 12 is provided to define the waterlev el in the boiler. A filling aperture 13 is provided in'thehorizontal wall and is located adjacent the outer wall of the boiler, that'is the one which will lie closejtothe wall of. thecontainer when the boilers are'in. position. A suitable closure such as a cork-emaybe-pro- Videdfor the fillingaperture. I

It will be understood that when water is supplijed t'o the filling aperture of-the boiler and the level in thefboiler rises to the hori- 'zontal wall, any 'fu'rther supply will over- "nipple 18 adapted-to receive a flexible tube by which steam is conveyed to the curler. The tubular seating is provided with a second pair of apertures 19, 20 in the upper part of the tube, the aperture 20 connecting to a tube 22 projecting into a safety valve connection 23.

The tubular seating 14 is adapted to accommodate a valve member 24 which comprises a rod adapted to be moved longitudinally within the seating member. According to the position of the valve steam may pass into the tube 22, seating member 14 and downtake 17 or alternately through port 19, seating member 14 and port 15 to the atmosphere.

When the path to the downfiow 17 is open, the valve 24 will close the apertures 15, 19, while when the by-pass to the atmosphere is open, the valve will close the apertures 16, 20.

The valve is adapted to be operated by a spindle 25 which projects through a closing cap 26 and is provided with a suitable handle or knob 30.

' The cap '26 is screwed or otherwise removably secured in the end of the seating member 14 and forms a shoulder to locate the valve when in position to close the by-pass.

It may happen that a slight escape of moisture may occur between the spindle 25 and the closing cap 26 and such will be collected by the drip tray 31 which extends beyond the wall of the container.

It is preferred that the apertures 16 and 20 should be in alignment whereby stoppages of the pipe 17 and nipple 18 may be cleared by inserting a wire through the pipe 22.

In inserting the boiler into the container the valve rod may be removed together with the closing cap 26. and inserted'through a suitable hole in the, container and the cap screwed home in the end of the seating member 14. Alternatively the wall may be slotted for the purpose.

The heating device may be of any suitable construction and preferably comprises an electric heater 27 of known form which is inserted intoa cavity formed in the boiler by means of a flat tube 28 which extends from the inner end of the boiler. By means of the valve device which permits the alternative path for the steam, the wiring for the heaters may be simplified as they can be'connected up in series as indicated in Figure 4 as it is found unnecessary to out out the heater when any desired boiler is not required, while by means of the independent cavity for the heater removal of the heater unit is facilitated when it is desired, for example, to change or renew an element.

A switch 29 is provided having a number of resistances whereby the heating may be adjusted as desired.

The bottom wall of the boiler may be provided with pressed up feet or projections so that the wall will be spaced from the floor of the container or tray.

The safety valve 11 maybe of any suitable form and as shown comprises a flat disc having a stem entering an aperture in the screwed cap.

What is claimed is:

1. Means for supplying steam to a hairwaving appliance, comprising a steam boiler, a tubular seating member project-ing through a wall of the boiler, a pair of apertures in the tubular seating permitting steam to enter the tubular'member and pass out to atmosphere, a second pair of apertures permitting steam to pass into the tubular member and thence to the'hair-waving-appliance, and a valve device located in the tubular seating adapted to cover and uncover the pairs of apertures alternatively.
